the Petersburg-Ratts Line.

Facilities Obligations Common To The Parties

1.06  Subject to accidents, strikes, litigation, delays in securing
delivery of equipment or other similar or dissimilar causes beyond the
reasonable control of the parties, including the procuring of the
necessary materials and labor and the obtaining of all the necessary
governmental authorizations and permits approving the use of such labor
and materials, the installation of the facilities to be provided by the
parties, as hereinabove described, shall be completed and in service on
or before June 1, 1982, (the "In-Service Date").  Should said facilities
be delayed beyond said date due to any of the aforesaid causes, it shall
nevertheless be completed as soon thereafter as practicable.

1.07  The parties shall cooperate to assure the maximum practicable
coordination of design and installation of the facilities to be installed
by each of them with new and existing facilities of the other.  Each
party agrees to promptly notify the other party of any potential delay in
the In-Service Date.

Synchronous Operation

1.08  When the installation of the facilities as provided for under this
Article 1 is completed, the systems of the parties shall be connected at
the Interconnection Point and thereafter throughout the duration of this
agreement, subject to the provisions of this Section 1.08 and Section
1.09, such systems shall be operated in continuous synchronism through
such line.  If synchronous operation of the systems through such line
becomes interrupted either manually or automatically because of reasons
beyond the control of either party or because of scheduled maintenance
that has been agreed to by both parties, the parties shall cooperate to
remove the cause of such interruption as soon as practicable and restore
such line to normal operating condition.  Neither party shall be
responsible to the other party for any damage or loss of revenue caused
by any such interruption.

1.09  The parties hereto agree that either party may interrupt
synchronous operation through this interconnection if either determines
that its facilities may be damaged due to excessive loadings, and such
loadings may be reduced or alleviated by such interruption.  If such
interruption occurs, the parties shall cooperate to remove the cause of
such loadings as soon as practicable and restore such interconnection to
normal operating condition.  Neither party shall be responsible to the
other party for damage or loss of revenue caused by such interruption.

The parties hereto further agree to study and negotiate the installation,
ownership, and cost of any additional equipment necessary to effect a
long term solution to any such excessive loading herein described in the
event either party determines that this interconnection contributes to
the excess loading and requests such negotiation.

Maintenance of Equipment

1.10  The parties hereto shall each keep the lines, together with all
associated equipment and appurtenances, described in Article 1 hereof
that are located on their respective sides of the Interconnection Point
in a suitable condition of repair at all times, each at its own expense,
in order that said lines will operate in a reliable  and satisfactory
manner and in order that reduction in the capacity of said lines will be
avoided to the extent practicable.

1.11  The parties hereto understand that IPL and Hoosier each now has its
transmission system interconnected with the electric transmission systems
of other electric utility companies and each has contracted for other
such interconnections and may hereafter during the term of this agreement
desire to make additional interconnections with such companies or with
other electric utility companies.  Each such additional interconnection
with another electric utility system shall be discussed between the
parties and if, in the opinion of either party, the establishment of such
interconnection will cause transfer of power or reactive power through
the system of either party during normal parallel operation to or from
the systems with which either party proposes to add an interconnection to
its system, then before any such additional interconnection is made,
joint load studies shall be carried on to determine the effect which such
interconnection will have on the transmission systems of the parties.  If
as the results of such studies it is the reasonable opinion of one of the
parties that the proposed additional interconnection would cause
unreasonable transfers of power or reactive power through the electric
transmission system of such party or otherwise impair the ability of such
party to carry out its own obligations, then the party proposing such
additional interconnection shall, before such proposed interconnection is
placed in service:

     1.111     agree to compensate the other party for the use of that
     portion of its facilities determined to be dedicated to the new
     situation caused by the establishment of the proposed
     interconnection; and/or

     1.112     install and/or remove such equipment as may be reasonably
     necessary to avoid such unreasonable transfers of power or reactive
     power; or

     1.113     abandon the establishment of such additional interconnection.

                            ARTICLE 3

                       SERVICE CONDITIONS

Control of System Disturbance

3.01  The parties hereto shall maintain and operate their respective
systems in accordance with sound operating practice so as to minimize the
likelihood of disturbance originating in either system which might cause
impairment to the service of the system of the other party or of any
system interconnected with the system of the other party.

Control of Kilovar Exchange

3.02  It is intended that neither party hereto shall be obligated to
deliver kilovars for the benefit of the other party; also that neither
party shall be obligated to receive kilovars when to do so may introduce
objectionable operating conditions on its system.  The Operating
Committee shall be responsible for the establishment from time to time of
operating procedures and schedules, in respect of carrying kilovar loads
by one system for the other in order to secure adequate service and
economical use of the facilities of both systems and in respect of proper
charges, if any, for the use of facilities carrying kilovar loads.  In
discharging such duties the Operating Committee shall recognize that in
the transmission and delivery of power and energy hereunder the carrying
of kilovar loads by either of the parties, in harmony with sound
engineering principles of transmission operation with their systems
interconnected, is subject to numerous variables contingent upon loading
and operating conditions existing simultaneously on both of their
systems.  The operating procedures and schedules so set up by the
Operating Committee shall be in accord with such principles and shall
require each of the parties to carry kilovar loads at such times and in
such amounts as will be equitable to both parties.

Control of Unscheduled Power Deliveries

3.03  The parties hereto shall exercise reasonable foresight in carrying
out all matters related to the providing and operating of their
respective electric power resources so as to minimize to the extent
practicable deviations between actual and scheduled deliveries of
electric power and energy between their systems.  The parties shall
provide and install on their respective systems such communication and
telemetering facilities as are essential to so minimize such deviations;
and, in developing and executing operating procedures that will enable
the parties to avoid, to the extent practicable, deviations from
scheduled deliveries, shall fully cooperate with each other and with
third parties whose systems are either directly or indirectly
interconnected with the systems of the parties and who of necessity,
together with the parties, must unify their efforts cooperatively to
achieve effective and efficient interconnected operation.  The parties
recognize, however, that, despite their best efforts to prevent the same,
unscheduled deliveries of electric energy from one party to the other may
occur.  In such events, electric energy delivered hereunder shall be
settled for either by the return of equivalent energy or by payment of
the out-of-pocket cost (such  cost being at the delivery point or points,
set forth in Section 4.01 of this agreement, taking into account
electrical losses incurred from the source or sources of such energy to
said delivery point or points) of electric energy delivered hereunder to
the supplying party plus ten percent of such cost.  If equivalent energy
is returned, it shall be returned at times when the load conditions of
the party receiving it are substantially equivalent to the load
conditions of such party at the time the energy for which it is returned
was delivered or, if such party elects to have equivalent energy returned
under different conditions, it shall be returned in such amounts, to be
agreed upon by the Operating Committee, as will compensate for the
difference in conditions.

special test may be made at the expense of the party requesting such
special test.  Representatives of both parties shall be afforded the
opportunity to be present at all routine or special tests and upon
occasions when any readings for purposes of settlements hereunder are
taken from meters not bearing an automatic record.

4.06  If, at any test of metering equipment an inaccuracy shall be
disclosed exceeding two percent, the account between the parties hereto
for service theretofore delivered shall be adjusted to correct for the
inaccuracy over the shorter of the following two periods:  (1) for the
thirty-day period immediately preceding the day of the test or (2) for
the period that such inaccuracy may be determined to have existed. 
Should the metering equipment provided for in Section 4.03 hereof at any
time fail to register, the electric power and energy delivered during
such failure shall be determined from the check meters, if installed, or
otherwise shall be determined from the best available data.

                            ARTICLE 5

                     RECORDS AND STATEMENTS

5.01  In addition to records of the metering provided for in Article 4
hereof, the parties hereto shall keep, in duplicate, such other records
as may be needed to afford a clear history of the various deliveries of
electric energy made, and of the clock-hour integrated demands in
kilowatthours delivered, by one party to the other.  In maintaining such
records, the parties shall effect such segregations and allocations of
demands and electric energy delivered into classes representing the
various services and conditions as may be needed to effect settlements
under this agreement.  The originals of all such records shall be
retained by the party keeping the records and the duplicates shall be
delivered monthly to the other party, unless the parties agree in writing
upon a different time interval for such delivery.

parties fail so to agree within a period of fifteen days from the receipt
of the original notice, the party calling for the arbitration shall, by
written notice to the other party, give notice for appointment of a board
of arbitrators skilled with respect to matters of the character involved
in the disagreement, naming one arbitrator in such notice.  The other
party shall, within ten days after the receipt of such notice, appoint a
second arbitrator, and the two arbitrators so appointed shall choose and
appoint a third arbitrator.  In case such other party fails to appoint an
arbitrator within said ten days, or in case the two so appointed fail for
ten days to agree upon and appoint a third, the party calling for the
arbitration, upon five days' written notice delivered to the other party,
shall apply to the senior Judge, in point of service, of the United
States District Court for the Southern District of Indiana, for
appointment of the second or third arbitrator, as the case may be.

10.03  The sole arbitrator, or the board of arbitrators, shall afford
adequate opportunity to the parties to present information with respect
to the matters submitted for arbitration and may request further
information from either or both parties.  The findings and award of the
sole arbitrator or of a majority of the board of arbitrators shall be
final and conclusive with respect to the question or questions submitted
for arbitration and shall be binding upon the parties; provided, that
such findings and award shall not in any way vary the expressed terms of
this agreement or in any way extend the expressed scope and intent
hereof.  Each party shall pay for the services and expenses of the
arbitrator appointed by or for it, if there is a board of arbitrators. 
All other costs incurred in connection with the arbitration shall be
divided in equal parts and paid by the parties accordingly, unless the
award shall specify a different division of such costs.

                                                                EXHIBIT I

                       SERVICE SCHEDULE A

                        EMERGENCY SERVICE

SECTION 1 - DURATION

1.1  This Service Schedule, being a part of an agreement dated as of
December 1, 1981, between Indianapolis Power & Light Company ("IPL") and
Hoosier Energy Rural Electric Cooperative, Inc. ("Hoosier") (the
"Agreement") shall become effective on the Interconnection Date as
defined in Article 9 of the Agreement and shall continue in effect until
termination of the Agreement.

SECTION 2 - SERVICES TO BE RENDERED

2.1  Subject to the provisions of subsection 2.2 of this Section 2, in
the event of a breakdown or other emergency in or on the system of either
party involving either sources of power or transmission facilities, or
both, impairing or jeopardizing the ability of the party suffering the
emergency to meet the loads of its system, the other party shall supply
to the party having the emergency such electric energy as the supplying
party is requested to deliver; provided, that neither party shall be
obligated to supply such emergency energy which, in the supplying party's
sole judgment, cannot be delivered without creating a hazard to or
economic burden upon its operations or without impairing or jeopardizing
the total load requirements of its system; and provided further, that
neither party shall be obligated to supply such emergency energy for a
period in excess of forty-eight consecutive hours during any single
emergency.

2.2  The parties recognize that the supply of electric energy as
provided for in subsection 2.1 of this Section 2 is subject to two
conditions which may preclude the delivery of such energy as so provided: 
(a) the party requested to deliver electric energy may be suffering an
emergency in or on its own system as described in said subsection 2.1, or
(b) the system of the party of whom such request is made may be
delivering electric energy, under a mutual emergency interchange
agreement, to the system of another interconnected company which is
suffering an emergency in or on its system.  Under conditions as cited
under (a) above, neither party shall be considered to be in default
hereunder if unable to comply with the provisions of said subsection 2.1. 
Under conditions as cited under (b) above, neither party shall be
considered to be in default hereunder if it is unable to comply with the
provisions of said subsection 2.1 provided that the aforesaid
interconnected company has suffered said emergency in or on its system
prior to and within forty-eight hours of that of the other party hereto
and that, if requested by said other party, such delivery of electric
energy to said interconnected company shall be discontinued within
forty-eight hours following the start of such delivery, and a subsequent
delivery shall be made for a full forty-eight hour period to said other
party in accordance with the provisions of said subsection 2.1.

2.3  If at any time the record over a reasonably prior period shows
clearly that either of the parties has failed to deliver energy in
accordance with and subject to the provisions of subsection 2.1 and
subsection 2.2 of this Section 2, either party, by written notice given
to the other party, may call for a joint study by the parties of the
reserve generating capacity in and provided for their respective systems
and of their respective system transmission facilities affecting the
supply and delivery of power and energy under the Agreement.  It shall be
the purpose of such study to determine the adequacy or inadequacy of
reserve generating capacity and transmission facilities being provided to
meet the requirements of the parties' respective systems, reflecting
obligations under the Agreement, and, if inadequate, the extent of the
burden that one party may be placing upon the other.  If it should be
found that one party is placing an unreasonable burden upon the other,
the party causing such burden shall take such measures as are necessary
to remove the burden from the other party, or the parties shall enter
into such arrangements as shall provide for equitable compensation to the
party being burdened.

SECTION 3 - COMPENSATION

3.1  Emergency Energy shall be settled for, at the option of the
supplying party, either by payment or by return of equivalent energy.

3.2  If the supplying party opts to receive payment for Emergency Energy
delivered, the receiving party shall pay the supplying party the greater
of:

     3.21      110% of the out-of-pocket cost of supplying such Emergency
               Energy that is generated from the supplying party's own
               system, and, for energy purchased by the supplying party from
               another system to supply any part of such Emergency Energy,
               100% of the amount paid by the supplying party therefor plus
               10% of that amount, not exceeding, however, 1.6 mills per
               kilowatthour; or

     3.22      30 mills per kilowatthour of such Emergency Energy

3.3  If the supplying party opts to receive equivalent energy for
Emergency Energy delivered, such equivalent energy shall be returned at
times when the load conditions of the party originally supplying
Emergency Energy are substantially equivalent to the load conditions of
such party that existed when the Emergency Energy was delivered or, if
such party elects to have equivalent energy returned under different
conditions, it shall be returned in such amounts and at such times as,
the Operating Committee agrees will compensate the original supplying
party, for the difference in conditions.

                       SERVICE SCHEDULE B

                         ENERGY TRANSFER

SECTION 1 - DURATION

1.1  This Service Schedule, being a part of an agreement dated as of
December 1, 1981, between Indianapolis Power & Light Company ("IPL") and
Hoosier Energy Rural Electric Cooperative, Inc. ("Hoosier") (the
"Agreement") shall become effective on the Interconnection Date as
defined in Article 9 of the Agreement and shall continue in effect until
termination of the Agreement.

SECTION 2 - TRANSFER ARRANGEMENT

2.1  In carrying out the interconnected operation of their respective
systems as provided for under the Agreement, energy being received by a
portion of one party's system from another portion of its system or to
the system of another interconnected company, may flow over the
transmission facilities of the other party as a natural result of the
physical and electrical characteristics of the interconnected network of
transmission lines to which the parties are connected.  Such flow of
energy may occur during periods when conditions of system operation are
normal or may occur during periods of emergency caused by the failure of
either sources of power or transmission facilities, or both.  In respect
to such flow of energy (hereinafter called "energy transfer") the parties
agree as follows:

     2.11      Such energy transfer over their respective transmission
               facilities shall be permitted whenever such transfer occurs;
               provided, that such energy transfer shall not be of such
               magnitude or duration as to affect adversely, or jeopardize
               the ability of, the party over whose system such energy
               transfers occur to render or accept service to or from
               companies with which it now has, or at any time hereafter may
               have contractual arrangements for the interchange of power or
               energy.

     2.12      The parties recognize that in carrying out the provisions of
               this Service Schedule, the above described energy transfer,
               either during periods when conditions of system operation are
               normal or during periods of emergency, or both, may
               eventually require the installation of additional
               transmission facilities in order that such energy transfer
               may be properly controlled to the end that the ability of the
               party over whose system such energy transfers occur to meet
               its own requirements, as described under 2.11 above, is not
               affected adversely or jeopardized.  In the event the need for
               such additional transmission facilities becomes apparent to
               either of the parties during any term of this Service
               Schedule, upon written notice given by either party to the
               other party and as soon as practicable following such notice,
               the parties shall jointly reexamine conditions relating to
               energy transfer.  In such reexamination, if called for, the
               parties shall agree upon such additional transmission
               facilities as may be required to be installed, if any, and
               upon an equitable basis for bearing the cost of installing,
               maintaining and operating such facilities, if installed.

SECTION 3 - POWER AND ENERGY ACCOUNTING

3.1  The parties recognize that energy transfers as described under
Section 2 of this Service Schedule, except for such amounts of electrical
losses as may be incurred because of such energy transfers, are the
simultaneous acceptance and delivery of like amounts of power and energy
by and from the system of the party over whose system such energy
transfers occur.  Power and energy associated with energy transfers,
including electrical losses associated therewith, shall be accounted for
each clock-hour as provided for under Article 5 of the Agreement.  Proper
consideration to such electrical losses will be in accordance with the
manner agreed upon by the Operating Committee.  It is understood by the
parties, however, that such electrical losses resulting from energy
transfers, to be taken as losses over and above the losses prevailing
under basic conditions agreed upon by the parties, shall be supplied
simultaneously by the party for whom such energy transfers are being
made.  The parties agree that initially such basic conditions will be
established as those that exist when the scheduled net delivery between
the systems of the parties, and between their respective systems and the
systems of other interconnected companies, is zero kilowatts.  It is
further understood that, from time to time, conditions may require the
establishment of different basic conditions for such purpose.  Either
party by written notice given to the other party may call for a prompt
reexamination and reconsideration of matters pertinent to the
establishment of said basic conditions, whenever such reexamination
appears to be warranted, and the parties will thereupon agree to effect
such changes in the basic conditions, if any, that will equitably
compensate the parties for such losses.  Should such reexamination be
required, a statement will be prepared by the parties which shall include
in detail the amounts of energy delivered and received by the parties
that are associated with energy transfer and the amounts of electrical
losses associated therewith.

                                                              EXHIBIT III

                       SERVICE SCHEDULE C

                        INTERCHANGE POWER

SECTION 1 - DURATION

1.1  This Service Schedule, being a part of an agreement dated as of
December 1, 1981, between Indianapolis Power & Light Company ("IPL") and
Hoosier Energy Rural Electric Cooperative, Inc. ("Hoosier") (the
"Agreement") shall become effective on the Interconnection Date as
defined in Article 9 of the Agreement and shall continue in effect until
termination of the Agreement.

SECTION 2 - SERVICES TO BE RENDERED

Economy Energy

2.1  Either party may arrange to purchase from the other party electric
energy ("Economy Energy") when it is possible to effect a saving thereby
and, when, in the sole judgment of the supplying party, such energy is
available.  Prior to each Economy Energy transaction, the amount of
energy, the time of its delivery, and the charge therefore shall be
determined by the parties.  Receipt or delivery of Economy Energy may
also be arranged with other interconnected systems not parties to this
Agreement.

Non-Displacement Energy

2.2  It is recognized that occasions will arise when transactions under
subsection 2.1 above will be impracticable although a party may have
electric energy (herein called "Non-Displacement Energy") which it is
willing to make available from surplus capacity from its own system or
from outside sources, or both and which can be utilized advantageously
for short intervals by the other party.  In such event, the party
desiring such receipt of energy shall notify the other party of the
extent to which it desires to obtain Non-Displacement Energy, and if the
other party, in its sole judgment, determines that Non-Displacement
Energy is available, schedules providing the periods and extent of use
shall be mutually agreed upon.  Neither party shall be obligated to make
any Non-Displacement Energy available to the other.

SECTION 3 - COMPENSATION

Economy Energy

3.1  The charge for Economy Energy purchased by either party from the
other shall be based on the principle that the purchasing party shall pay
the out-of-pocket cost of the supplying party such energy and that the
resulting savings to the purchasing party shall be equally shared by both
parties.

3.2  When Economy Energy is obtained from or delivered to other
interconnected systems not signatories to this Agreement, payments shall
be based on the out-of-pocket cost of the supplying party or system
providing the energy and an allocation of the gross savings to be
realized.  For such purpose, gross savings is defined as the difference
between the out-of-pocket cost of the purchasing party or system to
generate such energy, and the out-of-pocket cost of the supplying party
or system to provide such energy.  Such allocation shall be made as
provided in subsections 3.21 and 3.22 of this section.

     3.21      Each party or system participating in the transaction other
               than the supplying and purchasing parties or systems, shall
               be paid (a) its cost of purchasing the energy supplied, plus
               (b) its cost of any additional transmission losses incurred,
               plus (c) fifteen percent of the savings remaining after
               deducting all such costs for transmission losses.

     3.22      The supplying party or system shall be paid out-of-pocket
               costs of providing the energy, plus one-half of the gross
               savings remaining after deducting all (b) and (c) costs
               enumerated in section 3.21 above.  The receiving party or
               system shall be entitled to the other one-half of the such
               savings.

Non-Displacement Energy

3.3  Non-Displacement Energy delivered hereunder shall be settled for
either by return of equivalent energy or, at the option of the supplying
party, by payment of the out-of-cost of the supplying party in generating
or supplying such energy plus ten percent of such cost.  Such cost shall
be as of the delivery point or points, as provided for in Section 4.01 of
said Interconnection Agreement, and shall take into account the
electrical losses incurred from the source or sources of such energy to
said delivery point or points.  If equivalent energy is returned, it
shall be returned at times when the load conditions of the receiving
party are equivalent to the load conditions of such party at the time the
energy was delivered.  If such party elects to have equivalent energy
returned under different conditions, such energy shall be returned in
such amounts as will compensate the supplying party for the difference in
conditions as agreed by the Operating Committee.

                       SERVICE SCHEDULE D

                        SHORT TERM POWER

SECTION 1 - DURATION

1.1  This Service Schedule, being a part of an agreement dated as of
December 1, 1981, between Indianapolis Power & Light Company ("IPL") and
Hoosier Energy Rural Electric Cooperative, Inc. ("Hoosier") (the
"Agreement") shall become effective on the Interconnection Date as
defined in Article 9 of the Agreement and shall continue in effect until
termination of the Agreement.

SECTION 2 - SERVICES TO BE RENDERED

2.1  Either party, by giving the other party sufficient notice, may
reserve for periods of one or more days or weeks, such electric power
(herein called "Short Term Power") as the supplying party at that time
may have and is willing to supply as Short Term Power.  The party asked
to supply Short Term Power shall be the sole judge as to the amounts and
periods that it has electric power available that may be reserved by the
other party as Short Term Power.  As used herein, the term "week" shall
mean any seven consecutive days.

2.2  The party desiring to reserve Short Term Power shall specify in a
notice to the other party the number of kilowatts and the period for
which it desires to reserve such power and the desired delivery schedule
for such power.  The supplying party shall promptly acknowledge receipt
of such notice and, shall signify the extent of its ability and
willingness to supply power in accordance with the provisions of such
notice.  Any such notice or acknowledgement thereof initially may be
given orally; however if requested by either party, it shall be confirmed
in writing and such confirmation shall be forwarded not later than the
third day following the day such oral notice is given, excluding
Saturdays, Sundays and holidays.

2.3  During the period the Short Term Power has been reserved as
provided in Section 2.2 above, the supplying party shall deliver upon
call electric energy (herein called "Short Term Energy") to the other
party at the delivery point or points set forth in Section 4.01 of the
Agreement in amounts not to exceed the number of kilowatts reserved. 
However, in the event conditions arise during such period which could not
have been reasonably foreseen at the time Short Term Energy was reserved
and such conditions would cause the delivery of said power to be
burdensome to the supplying party, said party shall have the right to
require the purchasing party to reduce for any portion of such period the
amount of such energy being taken to the amount specified by the
supplying party.  The purchasing party shall promptly comply with such
requirement of the supplying party.

SECTION 3 - COMPENSATION

3.1  The purchasing party shall pay the supplying party;

     3.11  For any week that Short Term Power is reserved, $1.05 per
     kilowatt reserved; less, for each day during any part of which the
     amount of such Short Term Power is reduced by the supplying party,
     $0.18 per kilowatt of the reduction (except that in no event shall
     the total of such deductions in any week exceed $1.05 per
     kilowatt).  For each period less than one week that Short Term
     Power is reserved, $0.18 per kilowatt reserved per day; less, for
     any day during any part of which the amount of Short Term Power is
     reduced by the supplying party, $0.18 per kilowatt of the
     reduction; plus

     3.12  110% of the out-of-pocket cost of supplying the Short Term
     Energy taken during such reservation periods that comes from the
     supplying party's own system; plus, for energy purchased by the
     supplying party from another system to supply any part of the Short
     Term Energy taken during such reservation periods, 100% of the
     amount paid therefore by the supplying party plus 10% thereof not
     to exceed 1.6 mills per kilowatthour.

                       SERVICE SCHEDULE E

                    LIMITED TERM POWER (FIRM)

SECTION 1 - DURATION

1.1  This Service Schedule, being a part of an agreement dated as of
December 1, 1981, between Indianapolis Power & Light Company ("IPL") and
Hoosier Energy Rural Electric Cooperative, Inc. ("Hoosier") (the
"Agreement") shall become effective on the Interconnection Date as
defined in Article 9 of the Agreement and shall continue in effect until
termination of the Agreement.

SECTION 2 - SERVICES TO BE RENDERED

2.1  Either party by giving the other party notice may reserve for
periods of not less than one (1) or more than twelve (12) months, such
electric power (herein called "Limited Term Power (Firm)") as the other
party may be willing to make available as Limited Term Power (Firm).  The
party asked to supply Limited Term Power (Firm) shall be the sole judge
as to the amounts and periods that it has electric power available that
may be reserved by the other party as Limited Term Power (Firm).

     2.11 To reserve Limited Term Power (Firm), the party desiring such
          power shall specify in its notice to the supplying party the
          number of kilowatts and the period for which it desires to so
          reserve such power.  The supplying party shall signify the
          extent of its ability and willingness to comply with the
          provisions of such notice.  Any notice or any acknowledgement
          of such notice that initially may be given orally shall be
          confirmed thereafter in writing.

     2.12      During each period that Limited Term Power (Firm) has been
               reserved as above provided, the supplying party shall deliver
               upon call electric energy (herein called "Limited Term Energy
               (Firm)") to the other party at the delivery point or points
               set forth in Section 4.01 of Article 4 of the Agreement in
               any amount up to and including the number of kilowatts
               reserved.  However, in the event conditions arise during such
               period which could not have been reasonably foreseen at the
               time said power was reserved and such conditions would cause
               the delivery of Limited Term Energy (Firm) to be burdensome
               to the supplying party, the supplying party may, upon notice
               to the reserving party reduce or interrupt the delivery of
               such energy to preserve the integrity of, or to prevent or
               limit any instability on, its system.

     2.13      The Limited Term Power (Firm) billing demand for any period
               shall be taken as equal to the number of kilowatts reserved
               as Limited Term Power (Firm) for such period.

SECTION 3 - COMPENSATION

3.1  The reserving party shall pay the supplying party:

     3.1  For any month that Limited Term Power (Firm) is reserved,
     $5.50 per kilowatt reserved; plus,

     3.12 110% of the out-of-pocket costs of supplying the Limited Term
     Energy (Firm) taken during such reserved periods that is generated
     by the supplying party, plus, for energy purchased by the supplying
     party from another system to supply any part of the Limited Term
     Energy (Firm), 100% of the amount paid therefore by the supplying
     party, plus 10% thereof not to exceed 1.6 mills per kilowatthour.

defined in Article 9 of the Agreement and shall continue in effect until
termination of the Agreement.

SECTION 2 - DIVERSITY POWER

2.1  From time to time, because of differences in load patterns one of
the parties hereto may have excess capacity during one seasonal load
period at the same time the other party is experiencing its peak load
season.  At such time it may be to the parties' mutual advantage to
schedule exchange of certain portions of any such excess capacity.  Such

the parties, the party which purchases Diversity Power during one
seasonal load period shall be obligated to have available a like amount
of Diversity Power for the other party during the other seasonal load
period.

2.3  The party supplying Diversity Power shall provide reserve capacity
for the committed amount, equivalent to that provided for its own
customers, exclusive of customers with interruptible service contracts.

2.4  Energy associated with the reservation of Diversity Power shall be
scheduled by the purchasing party no less than 18 hours in advance of
receiving such energy.  Energy receipts for a Monday shall be scheduled
no later than noon of the preceding Friday.

SECTION 3 - COMPENSATION

3.1  Demand Charges - There shall be no demand charge for Diversity
Power.

3.2  Energy Charges - Energy shall be billed at out-of-pocket cost plus
ten percent of such cost.  In the event that any part of the
out-of-pocket cost includes energy purchased by the supplying Party, only
the energy portion of such purchase cost shall be included.  Any
associated charges for demand, transmission, or other burden shall be
excluded.

     facilities of Hoosier or with transmission facilities of another
     utility, or (ii) on the date that is five years after the effective
     date of said Modification No. 2 and Service Schedule G as
     established by the Federal Energy Regulatory Commission (FERC);
     provided, that in the event Hoosier is in the process of replacing
     IPL's transmission service under said Modification No. 2 and
     Service Schedule G, but, through no fault of its own, Hoosier is
     unable to consummate such replacement within the five-year term of
     said Modification No. 2 and Service Schedule G, then the term
     thereof may be extended for an additional period of not more than
     three years, upon adequate assurances being given to IPL by Hoosier
     that replacement of such transmission service by IPL to Hoosier
     will be accomplished within such additional period.  If Hoosier
     fails to make such assurances, or IPL deems them inadequate, such
     term shall not be extended.  Hoosier agrees, in connection with any
     such termination, that IPL may unilaterally file an appropriate
     notice of termination with FERC, in which filing Hoosier shall
     concur.  Hoosier hereby releases IPL from all obligations,
     contractual or otherwise, to provide electric transmission service

     Service Schedule G as hereinabove provided, and Hoosier agrees that
     after such termination it shall be required to rely exclusively
     upon its own electric transmission facilities or the electric
     transmission facilities of a utility other than IPL to supply
     electric power and energy to the Honey Creek Substation."

     G.  Article 10 thereof is hereby amended by adding a new Section

     "20.01  Default Defined.  As used herein, "Default" shall mean the
     failure of a party to make any payment or perform any obligation at
     the time and in the manner required by this agreement, except where
     such failure to discharge obligations (other than the payment of
     money) is the result of Force Majeure.  Failure to make any payment
     in the time and manner required by this agreement shall not be
     excused as a Default by payment of late charges in accordance with
     the provisions in Section 20.02 below.

     "20.02  Remedies For Default.  Upon failure of a party to make a
     payment or perform an obligation required hereunder, the other
     party shall give written notice of Default to the defaulting party. 
     The defaulting party shall have thirty (30) days within which to
     cure the Default.  If a Default is not cured within such period,
     the party not in Default, at its option, may, in addition to all
     other rights and remedies available at law, in equity or under any
     other provision of this agreement:  (i) give notice to the

     such steps as such party deems necessary to cure the Default, or
     (ii) suspend this agreement for a period of 6 months, after which
     this agreement shall automatically terminate.  The defaulting party
     shall, in any event, pay to the other party the total of all
     additional costs reasonably incurred by such other party as a
     result of such Default and/or the curing of such Default,
     including, reasonable attorneys' fees, money reasonably paid to
     others, the reasonable equivalent in money for services of property
     obtained, and any other costs reasonably incurred by such other
     party in attempting to remedy such Default, together with interest
     on the total of such costs at the per annum rate of two (2) percent
     above the commercial lending rate as determined in Article 6
     hereof.  This provision is not intended as a liquidated damages
     provision or to limit liability in any way, and the party not in
     Default may also maintain such other actions for damages as may be
     provided by law, in equity or under this agreement."

                           "ARTICLE 21

                         "FORCE MAJEURE

     "21.02  Force Majeure.  The term "Force Majeure" shall mean any
     cause beyond the control of the party invoking the Force Majeure,
     including, but not limited to, failure or threat of failure of
     facilities, equipment or fuel supply, ice, act of God, flood,
     earthquake, storm, fire, lightning, explosion, epidemic, war, civil

     on suppliers or carriers; restraint by court order or other public
     authority or governmental agency, or action or non-action by, or
     failure to obtain the necessary authorizations or approvals from,
     or obtaining the necessary authorizations or approvals only subject
     to unreasonable restrictions from, any governmental agency or
     authority, which by the exercise of due diligence such party could
     not reasonably have been expected to avoid.  Nothing contained
     herein shall be construed to require a party to settle any strike,
     lockout, work stoppage or other industrial disturbance or dispute
     in which it may be involved or to take an appeal from any judicial,
     regulatory or administrative action.  Any party rendered unable to
     fulfill any of its obligations under this agreement by reason of
     Force Majeure shall exercise due diligence to remove such inability
     with all reasonable dispatch.  In the event either party is unable,
     in whole or in part, to perform any of its obligations by reason of
     Force Majeure the obligations of the party relying thereon, insofar
     as such obligations are affected by such Force Majeure, shall be
     suspended during the continuance thereof but no longer.  The party
     invoking the Force Majeure shall specifically state the full
     particulars of the Force Majeure and the time and date when the
     Force Majeure occurred.  Notices given by telephone under the
     provisions of this Article shall be confirmed in writing as soon as
     reasonably possible.  When the Force Majeure ceases, the party
     relying thereon shall give immediate notice thereof to the other
     party.  This agreement shall not be terminated by reason of Force
     Majeure but shall remain in full force and effect."

                        EMERGENCY SERVICE

SECTION 1 - DURATION

1.1  This Service Schedule, being a part of an agreement dated as of
December 1, 1981, between Indianapolis Power & Light Company ("IPL") and
Hoosier Energy Rural Electric Cooperative, Inc. ("Hoosier") (the
"Agreement") shall become effective on the Interconnection Date as
defined in Article 9 of the Agreement and shall continue in effect until
termination of the Agreement.

SECTION 2 - SERVICES TO BE RENDERED

2.1  Subject to the provisions of subsection 2.2 of this Section 2, in
the event of a breakdown or other emergency in or on the system of either
party involving either sources of power or transmission facilities, or
both, impairing or jeopardizing the ability of the party suffering the
emergency to meet the loads of its system, the other party shall supply
to the party having the emergency such electric energy as the supplying
party is requested to deliver; provided, that neither party shall be
obligated to supply such emergency energy which, in the supplying party's
sole judgment, cannot be delivered without creating a hazard to or
economic burden upon its operations or without impairing or jeopardizing
the total load requirements of its system; and provided further, that
neither party shall be obligated to supply such emergency energy for a
period in excess of forty-eight consecutive hours during any single
emergency.

2.2  The parties recognize that the supply of electric energy as
provided for in subsection 2.1 of this Section 2 is subject to two
conditions which may preclude the delivery of such energy as so provided: 
(a) the party requested to deliver electric energy may be suffering an
emergency in or on its own system as described in said subsection 2.1, or
(b) the system of the party of whom such request is made may be
delivering electric energy under a mutual emergency interchange
agreement, to the system of another interconnected company which is
suffering an emergency in or on its system.  Under conditions as cited
under (a) above, neither party shall be considered to be in default
hereunder if unable to comply with the provisions of said subsection 2.1. 
Under conditions as cited under (b) above, neither party shall be
considered to be in default hereunder if it is unable to comply with the
provisions of said subsection 2.1 provided that the aforesaid
interconnected company has suffered said emergency in or on its system
prior to and within forty-eight hours of that of the other party hereto
and that, if requested by said other party, such delivery of electric
energy to said interconnected company shall be discontinued within
forty-eight hours following the start of such delivery, and a subsequent
delivery shall be made for a full forty-eight hour period to said other
party in accordance with the provisions of said subsection 2.1.

2.3  If at any time the record over a reasonably prior period shows
clearly that either of the parties has failed to deliver energy in
accordance with and subject to the provisions of subsection 2.1 and
subsection 2.2 of this Section 2, either party, by written notice given
to the other party, may call for a joint study by the parties of the
reserve generating capacity in and provided for their respective systems
and of their respective system transmission facilities affecting the
supply and delivery of power and energy under the Agreement.  It shall be
the purpose of such study to determine the adequacy or inadequacy of
reserve generating capacity and transmission facilities being provided to
meet the requirements of the parties' respective systems, reflecting
obligations under the Agreement, and, if inadequate, the extent of the
burden that one party may be placing upon the other.  If it should be
found that one party is placing an unreasonable burden upon the other,
the party causing such burden shall take such measures as are necessary
to remove the burden from the other party, or the parties shall enter
into such arrangements as shall provide for equitable compensation to the
party being burdened.

SECTION 3 - COMPENSATION

3.1  Emergency Energy shall be settled for, at the option of the
supplying party, either by payment or by return of equivalent energy.

3.2  If the supplying party opts to receive payment for Emergency Energy
delivered, the receiving party shall pay the supplying party the greater
of:

     3.21      110% of the out-of-pocket cost of supplying such Emergency
               Energy that is generated from the supplying party's own
               system, and, for energy purchased by the supplying party from
               another interconnected system which is not a signatory to
               this Agreement ("Third Party") at the request of the
               receiving party, 100% of the amount paid to such Third Party
               plus up to 3.46 mills per kilowatthour (consisting of up to
               2.46 mills per kilowatthour for a transmission charge and 1
               mill per kilowatthour for difficult to quantify energy
               related costs) plus any transmission losses.

     3.22      30 mills per kilowatthour of such Emergency Energy

3.3  If the supplying party opts to receive equivalent energy for
Emergency Energy delivered; such equivalent energy shall be returned at
times when the load conditions of the party originally supplying
Emergency Energy are substantially equivalent to the load conditions of
such party that existed when the Emergency Energy was delivered or, if
such party elects to have equivalent energy returned under different
conditions, it shall be returned in such amounts and at such times as,
the Operating Committee agrees will compensate the original supplying
party, for the difference in conditions.

                             AMENDED
                       SERVICE SCHEDULE B

                         ENERGY TRANSFER

SECTION 1 - DURATION

1.1  This Service Schedule, being a part of an agreement dated as of
December 1, 1981, between Indianapolis Power & Light Company ("IPL") and
Hoosier Energy Rural Electric Cooperative, Inc. ("Hoosier") (the
"Agreement") shall become effective on the Interconnection Date as
defined in Article 9 of the Agreement and shall continue in effect until
termination of the Agreement.

SECTION 2 - TRANSFER ARRANGEMENT

2.1  In carrying out the interconnected operation of their respective
systems as provided for under the Agreement, energy being received by a
portion of one party's system from another portion of its system or to
the system of another interconnected company, may flow over the
transmission facilities of the other party as a natural result of the
physical and electrical characteristics of the interconnected network of
transmission lines to which the parties are connected.  Such flow of
energy may occur during periods when conditions of system operation are
normal or may occur during periods of emergency caused by the failure of
either sources of power or transmission facilities, or both.  In respect
to such flow of energy (hereinafter called "energy transfer") the parties
agree as follows:

     2.11      Such energy transfer over their respective transmission
               facilities shall be permitted whenever such transfer occurs;
               provided, that such energy transfer shall not be of such
               magnitude or duration as to affect adversely, or jeopardize
               the ability of, the party over whose system such energy
               transfers occur to render or accept service to or from
               companies with which it now has, or at any time hereafter may
               have contractual arrangements for the interchange of power or
               energy.

     2.12      The parties recognize that in carrying out the provisions of
               this Service Schedule, the above-described energy transfer,
               either during periods when conditions of system operation are
               normal or during periods of emergency, or both, may
               eventually require the installation of additional
               transmission facilities in order that such energy transfer
               may be properly controlled to the end that the ability of the
               party over whose system such energy transfers occur to meet
               its own requirements, as described under 2.11 above, is not
               affected adversely or jeopardized.  In the event the need for
               such additional transmission facilities becomes apparent to
               either of the parties during any term of this Service
               Schedule, upon written notice given by either party to the
               other party and as soon as practicable following such notice,
               the parties shall jointly reexamine conditions relating to
               Energy Transfer.  In such reexamination, if called for, the
               parties shall agree upon such additional transmission
               facilities as may be required to be installed, if any, and
               upon an equitable basis for bearing the cost of installing,
               maintaining and operating such facilities, if installed.

SECTION 3 - POWER AND ENERGY ACCOUNTING

3.1  The parties recognize that energy transfers as described under
Section 2 of this Service Schedule, except for such amounts of electrical
losses as may be incurred because of such energy transfers, are the
simultaneous acceptance and delivery of like amounts of power and energy
by and from the system of the party over whose system such energy
transfers occur.  Power and energy associated with energy transfers,
including electrical losses associated therewith, shall be accounted for
each clock-hour as provided for under Article 5 of the Agreement.  Proper
consideration to such electrical losses will be in accordance with the
manner agreed upon by the Operating Committee.  It is understood by the
parties, however, that such electrical losses resulting from energy
transfers, to be taken as losses over and above the losses prevailing
under basic conditions agreed upon by the parties, shall be supplied
simultaneously by the party for whom such energy transfers are being
made.  The parties agree that initially such basic conditions will be
established as those that exist when the scheduled net delivery between
the systems of the parties, and between their respective systems and the
systems of other interconnected companies, is zero kilowatts.  It is
further understood that, from time to time, conditions may require the
establishment of different basic conditions for such purpose.  Either
party by written notice given to the other party may call for a prompt
reexamination and reconsideration of matters pertinent to the
establishment of said basic conditions, whenever such reexamination
appears to be warranted, and the parties will thereupon agree to effect
such changes in the basic conditions, if any, that will equitably
compensate the parties for such losses.  Should such reexamination be
required, a statement will be prepared by the parties which shall include
in detail the amounts of energy delivered and received by the parties
that are associated with energy transfer and the amounts of electrical
losses associated therewith.

                       SERVICE SCHEDULE C

                        INTERCHANGE POWER

SECTION 1 - DURATION

1.1  This Service Schedule, being a part of an agreement dated as of
December 1, 1981, between Indianapolis Power & Light Company ("IPL") and
Hoosier Energy Rural Electric Cooperative, Inc. ("Hoosier") (the
"Agreement") shall become effective on the Interconnection Date as
defined in Article 9 of the Agreement and shall continue in effect until
termination of the Agreement.

SECTION 2 - SERVICES TO BE RENDERED

Economy Energy

2.1  Either party may arrange to purchase from the other party electric
energy ("Economy Energy") when it is possible to effect a saving thereby
and, when in the sole judgment of the supplying party, such energy is
available.  Prior to each Economy Energy transaction, the amount of
energy, the time of its delivery, and the charge therefore shall be
determined by the parties.  Receipt or delivery of Economy Energy may
also be arranged with other interconnected systems not parties to this
Agreement.

Non-Displacement Energy

2.2  It is recognized that occasions will arise when transactions under
subsection 2.1 above will be impracticable although a party may have
electric energy (herein called "Non-Displacement Energy") which it is
willing to make available from surplus capacity from its own system or
from outside sources, or both and which can be utilized advantageously
for short intervals by the other party.  In such event, the party
desiring such receipt of energy shall notify the other party of the
extent to which it desires to obtain Non-Displacement Energy, and if the
other party, in its sole judgment, determines that Non-Displacement
Energy is available, schedules providing the period and extent of use
shall be mutually agreed upon.  Neither party shall be obligated to make
any Non-Displacement Energy available to the other.

SECTION 3 - COMPENSATION

Economy Energy

3.1  The charge for Economy Energy purchased by either party from the
other shall be based on the principle that the purchasing party shall pay
the out-of-pocket cost of the supplying party such energy and that the
resulting savings to the purchasing party shall be equally shared by both
parties.

3.2  When Economy Energy is obtained from or delivered to a system
interconnected with either of the Parties which is not a signatory in the
Agreement ("Third Party"), payments among the participants in such a
transaction shall be based on the out-of-pocket costs of the supplying
party or Third Party providing the Energy and an allocation of the gross
savings, which are defined as the difference between (1) what the out-of-
pocket costs of the receiving party or Third Party would have been to
generate such Energy, and (2) the out-of-pocket costs of the supplying
party or Third Party providing the Energy.  Such allocation shall be made
as provided in subsection 3.21 and 3.22 hereinbelow.

     3.21      The transmitting party shall be paid (A) its cost of
               purchasing the Energy supplied, plus (B) its costs of any
               additional transmission losses incurred, plus (C) the greater
               of fifteen percent of the gross savings remaining after
               deducting all such payments for transmission losses or an
               amount up to 3.46 mills per kilowatthour of Energy received
               for transmission.

     3.22      The supplying party or Third Party shall be paid its out-
               of-pocket costs of providing the Energy, plus one-half of the
               gross savings remaining after deducting all payments made
               under subsection 3.21.

Non-Displacement Energy

3.3  Non-Displacement Energy delivered hereunder that is generated by
the supplying party's system shall be settled for either by return of
equivalent Energy or, at the option of the supplying party, by the
payment of the out-of-pocket costs of the supplying party generating such
Energy plus ten percent of such cost.  If equivalent Energy is returned,
it shall be returned at times when load conditions of the receiving party
are equivalent to the load condition of such party at the time the energy
was delivered or, different conditions, such energy shall be returned in
such amounts, to be agreed upon by the operating committee, as will
compensate for the difference in conditions.

3.4  Non-Displacement Energy delivered under subsection 2.2 above that is
purchased by the supplying party from another interconnected system at
the request of the receiving party shall be settled for by the payment of
100 percent of the amount paid to such Third Party, plus up to 3.46 mills
per kilowatthour (consisting of up to 2.46 mills per kilowatthour for a
transmission charge plus 1 mill per kilowatthour for difficult to
quantify energy related costs) plus any transmission losses.

                        SHORT TERM POWER

SECTION 1 - DURATION

1.1  This Service Schedule, being a part of an agreement dated as of
December 1, 1981, between Indianapolis Power & Light Company ("IPL") and
Hoosier Energy Rural Electric Cooperative, Inc. ("Hoosier") (the
"Agreement") shall become effective on the Interconnection Date as
defined in Article 9 of the Agreement and shall continue in effect until
termination of the Agreement.

SECTION 2 - SERVICES TO BE RENDERED

2.1  Either party, by giving the other party sufficient notice, may
reserve for periods of one or more days or weeks, such electric power
(herein called "Short Term Power") as the supplying party at that time
may have and is willing to supply as Short Term Power.  The party asked
to supply Short Term Power shall be the sole judge as to the amounts and
periods that it has electric power available that may be reserved by the
other party as Short Term Power.  As used herein, the term "week" shall
mean any seven consecutive days.

2.2  The party desiring to reserve Short Term Power shall specify in a
notice to the other party the number of kilowatts and the period for
which it desires to reserve such power and the desired delivery schedule
for such power.  The supplying party shall promptly acknowledge receipt
of such notice and, shall signify the extent of its ability and
willingness to supply power in accordance with the provisions of such
notice.  Any such notice or acknowledgement thereof initially may be
given orally; however if requested by either party, it shall be confirmed
in writing and such confirmation shall be forwarded not later than the
third day following the date such oral notice is given, excluding
Saturdays, Sundays and holidays.

2.3  During the period the Short Term Power has been reserved as
provided in Section 2.2 above, the supplying party shall deliver upon
call electric energy (hereincalled "Short Term Energy") to the other
party at the delivery point or points set forth in Section 4.01 of the
Agreement in amounts not to exceed the number of kilowatts reserved. 
However, in the event conditions arise during such period which could not
have been reasonably foreseen at the time Short Term Energy was reserved
and such conditions would cause the delivery of said power to be
burdensome to the supplying party, said party shall have the right to
require the purchasing party to reduce for any portion of such period the
amount of such energy being taken to the amount specified by the
supplying party.  The purchasing party shall promptly comply with such
requirement of the supplying party.

SECTION 3 - COMPENSATION

3.1  The Party reserving Weekly or Daily Short Term Power shall pay the
supplying party the following Demand Charges:

     3.11      WEEKLY SHORT TERM POWER -- For any week that Short Term
               Power is reserved, up to $1.05 per kilowatt reserved;
               less, for each day during any part of which the amount
               of Weekly Short Term Power is reduced upon notice from
               the supplying party, one-sixth (1/6) of the supplying
               party's weekly demand rate per kilowatt for each
               kilowatt reduction but not more than the rate agreed
               upon for each kilowatt per month.

     3.12 DAILY SHORT TERM POWER -- For any day that Short Term Power
          is reserved, up to $0.21 per kilowatt reserved; less, for
          each day during which the amount of Daily Short Term Power is
          reduced upon notice by the supplying party, the demand charge
          per kilowatt for each day during which any such reduction is
          in effect shall be waived for each kilowatt of reduction.

     3.13 THIRD PARTY WEEKLY SHORT TERM POWER -- For any week that
          Weekly Short Term Power is reserved from a Third Party by the
          supplying party for and at the request of the receiving
          party, such Short Term Power shall be supplied at the rate of
          up to $0.295 per kilowatt reserved per week plus the demand
          charge paid therefore by the supplying party to the Third
          Party in the event the amount of Weekly Short Term Power
          reserved from a Third Party is reduced upon the request of
          the Third Party, the demand charge for each day during which
          such reduction is in effect shall be reduced by the amount of
          which the demand charge payable by the supplying party is
          reduced under its Agreement with such Third Party plus,
          one-sixth (1/6) of the rate per kilowatt agreement upon under
          this paragraph for each kilowatt of reduction per day, but
          not more than the rate agreed upon for each kilowatt per
          week.

     3.14 THIRD PARTY DAILY SHORT TERM POWER -- For any day that Daily
          Short Term Power is reserved from a Third Party by the
          supplying party for and at the request of the receiving
          party, such Short Term Power shall be supplied at the rate of
          up to $0.059 per kilowatt reserved per day plus the demand
          charge paid therefore by the supplying party to the Third
          Party.  In the event the amount of Daily Short Term Power
          reserved from a Third Party is reduced upon the request of
          the Third Party, the demand charge for each day during which
          such reduction is in effect shall be reduced by the amount by
          which the demand charge payable by the supplying party is
          reduced under its Agreement with such Third Party plus, the
          rate per kilowatt agreed upon under this paragraph for each
          kilowatt of said reduction.

3.2  The reserving party shall pay the supplying party for all Weekly or
Daily Short Term Energy delivered at the following rates:

     3.21 For each kilowatthour that is generated by the supplying
          party's system, 100 percent of the out-of-pocket costs of
          supplying Short Term Energy called for during such period,
          plus 10 percent of such costs.

     3.22 For each kilowatthour purchased by the supplying party from a
          Third Party in order to supply the Short Term Energy called
          for during such period, 100 percent of the amount of the
          Energy charge paid therefore by the supplying party plus 1
          mill per kilowatthour plus any transmission losses.

                    LIMITED TERM POWER (FIRM)

SECTION 1 - DURATION

1.1  This Service Schedule, being a part of an agreement dated as of
December 1, 1981, between Indianapolis Power & Light Company ("IPL") and
Hoosier Energy Rural Electric Cooperative, Inc. ("Hoosier") (the
"Agreement") shall become effective on the Interconnection Date as
defined in Article 9 of the Agreement and shall continue in effect until
termination of the Agreement.

SECTION 2 - SERVICES TO BE RENDERED

2.1  Either party by giving the other party notice may reserve for
periods of not less than one (1) or more than twelve (12) months, such
electric power (hereincalled "Limited Term Power (Firm)") as the other
party may be willing to make available as Limited Term Power (Firm).  The
party asked to supply Limited Term Power (Firm) shall be the sole judge
as to the amounts and periods that it has electric power available that
may be reserved by the other party as Limited Term Power (Firm).

     2.11 To reserve Limited Term Power (Firm), the party desiring such
          power shall specify in its notice to the supplying party the
          number of kilowatts and the period for which it desires to so
          reserve such power.  The supplying party shall signify the
          extent of its ability and willingness to comply with the
          provisions of such notice.  Any notice or any acknowledgement
          of such notice that initially may be given orally shall be
          confirmed thereafter in writing.

     2.12      During each period that Limited Term Power (Firm) has been
               reserved as above provided, the supplying party shall deliver
               upon call electric energy (herein called "Limited Term Energy
               (Firm)") to the other party at the delivery point or points
               set forth in Section 4.01 of Article 4 of the Agreement in
               any amount up to and including the number of kilowatts
               reserved.  However, in the event conditions arise during such
               period which could not have been reasonably foreseen at the
               time said power was reserved and such conditions would cause
               the delivery of Limited Term Energy (Firm) to be burdensome
               to the supplying party, the supplying party may, upon notice
               to the reserving party reduce or interrupt the delivery of
               such energy to preserve the integrity of, or to prevent or
               limit any instability on, its system.

     2.13      The Limited Term Power (Firm) billing demand for any period
               shall be taken as equal to the number of kilowatts reserved
               as Limited Term Power (Firm) for such period.

SECTION 3 - COMPENSATION

3.1  The party reserving Limited Term Power (Firm) shall pay the
supplying party the following Demand Charges:

     3.11 MONTHLY LIMITED TERM POWER (FIRM) -- For any month that
          Limited Term Power (Firm) is reserved, up to $5.50 per
          kilowatt reserved; less, for each day during any part of
          which the amount of Monthly Limited Term Power (Firm) is
          reduced upon notice from the supplying party, one-twentieth
          (1/20) of the supplying party's monthly demand rate per
          kilowatt for each kilowatt of reduction but not more than the
          rate agreed upon for each kilowatt per month.

     3.12 THIRD PARTY MONTHLY LIMITED TERM POWER (FIRM) -- For any
          month that Monthly Limited Term Power (Firm) is reserved from
          a Third Party by the supplying party for and at the request
          of the receiving party, such Monthly Limited Term Power
          (Firm) shall be supplied at the rate of up to $1.28 per
          kilowatt reserved per month plus the demand charge paid
          therefore by the supplying party to the Third Party.  In the
          event the amount of Monthly Limited Term Power (Firm)
          reserved from a Third Party is reduced upon the request of
          the Third Party, the demand charge for each day during which
          such reduction is in effect shall be reduced by the amount by
          which the demand charge payable by the supplying party is
          reduced under its Agreement with such Third Party plus,
          one-thirtieth (1/30) of the rate per kilowatt agreed upon
          under this paragraph for each kilowatt of reduction per day,
          but not more than the rate agreed upon for each kilowatt per
          month.

3.2  The reserving party shall pay the supplying party for all Monthly
Limited Term Energy (Firm) delivered at the following rates:

     3.21 For each kilowatthour that is generated by the supplying
          party's system, 100 percent of the out-of-pocket costs for
          supplying Limited Term Energy (Firm) called for during such
          period, plus 10 percent of such costs.

     3.22 For each kilowatthour purchased by the supplying party from a
          Third Party in order to supply the Limited Term Energy (Firm)
          called for during such period, 100 percent of the amount of
          the Energy charge paid therefore by the supplying party plus
          1 mill per kilowatthour plus any transmission losses.

defined in Article 9 of the Agreement and shall continue in effect until
termination of the Agreement.

SECTION 2 - DIVERSITY POWER

2.1  From time to time, because of differences in load patterns one of
the parties hereto may have excess capacity during one seasonal load
period at the same time the other party is experiencing its peak load
season.  At such time it may be to the parties' mutual advantage to
schedule exchange of certain portions of any such excess capacity.  Such
capacity shall be termed and is herein called "Diversity Power".

2.2  At any time Diversity Power transactions are agreed upon between
the parties, the party which purchases Diversity Power during one
seasonal load period shall be obligated to have available a like amount
of Diversity Power for the other party during the other seasonal load
period.  Seasonal load period shall mean for the Summer seasonal load
Period, the months of April thru September and for the Winter seasonal

                               AND
         HOOSIER ENERGY RURAL ELECTRIC COOPERATIVE, INC.


THIS AMENDMENT made and entered into as of the 1st day of January, 1995
by Indianapolis Power & Light Company ("IPL"), being an Amendment to the
Interconnection Agreement between Hoosier Energy Rural Electric
Cooperative, Inc. ("Buyer") and IPL dated December 1, 1981 (the
"Agreement").


                           WITNESSETH:


WHEREAS, IPL and Hoosier Energy Rural Electric Cooperative, Inc., entered
into the Agreement on December 1, 1981, which Agreement has been amended
from time to time;


WHEREAS, the Agreement provides for the sale of power and energy by IPL 
under Service Schedules described as:
          Service Schedule A            Emergency Service
          Service Schedule C            Interchange Power
          Service Schedule D            Short Term Power
          Service Schedule E            Limited Term Power
                                         (Firm)
          Service Schedule F            Diversity Power


WHEREAS, the Agreement provides for the recovery of incremental costs or
"out-of-pocket" costs occasioned by the sale by IPL of electric energy;


WHEREAS, IPL has implemented its Emissions Constrained Dispatch Plan,
attached hereto;


WHEREAS, the rates for Emergency Service, Interchange Power, Short Term
Power, Limited Term Power (Firm), and Diversity Power, do not expressly
include the cost of replacing sulfur dioxide ("SO2") emission allowances
expended in order to provide such energy in compliance with Federal laws
governing SO2 emission;


WHEREAS, IPL desires to amend the Agreement to clarify recovery of out-
of-pocket costs occasioned by the sale of said energy as including the
recovery of the incremental cost of SO2 emission allowances; 


NOW, THEREFORE, in consideration of the premises and the terms and
conditions set forth herein; IPL desires to amend the Agreement as
follows:

Section 1.     Compensation for SO2 Emission Allowances.
The Buyer shall compensate IPL for the consumption of Sulfur Dioxide
Emissions Allowances ("SO2 Allowances") directly attributed to electric
energy sales by IPL to Buyer under the Service Schedules.  Such
compensation shall, at Buyer's option, be made by either supplying IPL
with the number of SO2 Allowances directly attributed to such energy
sales, or by reimbursing IPL for the incremental cost of such number of
SO2 Allowances, rounded to the nearest whole SO2 Allowance.


If Buyer opts to reimburse IPL in cash for SO2 Allowances associated with
Buyer's energy purchases for the month, the cash amount due at billing
will be determined by multiplying the number of SO2 Allowances attributed
to the sale by the incremental cost of the SO2 Allowances, as determined
in Section 2.2, at the time of the sale.


If Buyer opts to reimburse IPL in SO2 Allowances, Buyer will record or
transfer to IPL's account, the number of SO2 Allowances calculated below,
at the time cash settlement for the energy is due.  In all cases, Buyer
will transfer to IPL's account the number of SO2 Allowances due IPL for
calendar year no later than January 15 of the following year.  "Transfer
to IPL's account" shall mean, for purposes of the Amendment, the transfer
by the USEPA of the requisite number of SO2 Allowances to IPL's Allowance
Tracking System account and the receipt by IPL of the Allowance Transfer
Confirmation.


Section 2.     Determination of SO2 Emission Allowances Due IPL.
     Section 2.1.   Number of SO2 Allowances
     The number of SO2 Allowances directly attributed to an energy sale
     made by IPL shall be determined for each hour, by determining the
     contribution from each of the unit(s) from which the energy sale is
     being made for that hour.  For each unit, the emission rate in
     pounds of SO2 per million Btu will be determined each month, from
     fuel sulfur content, control equipment performance, and continuous
     emissions monitoring data.  The emission rate and the unit heat
     rate will be used to determine the SO2 Allowances used per
     megawatt-hour ("MWH").  The energy from each unit attributable to
     the sale, and the SO2 Allowances per MWH for each unit, will be
     used to determine the number of SO2 Allowances attributable to the
     sale.


     Section 2.2 .  Cost of SO2 Allowances
     The incremental SO2 Allowance cost used to determine economic
     dispatch of IPL's generating units in any month, will also be the
     basis used to determine compensation for IPL's energy sales.  The
     incremental SO2 Allowances cost, in dollars per ton of SO2, shall
     be determined each month and will be based on the Cantor Fitzgerald
     offer  price for SO2 Allowances, or if such is not available, the
     another nationally recognized SO2 Allowance trading market price or
     market price index, at the beginning of the month.  The SO2
     Allowance value may be changed at any time during the month to
     reflect the more current incremental cost, or market price, for SO2
     Allowances.  Buyer will be notified of the new SO2 Allowance value
     prior to dispatch of IPL energy to Buyer.  


Section 3.     Effective Date.
This Amendment to the Agreement shall be made effective as of January 1,
1995.

IN WITNESS WHEREOF, IPL has caused the foregoing Amendment to be signed
by its duly authorized officer, effective as of the date set forth above.

                              INDIANAPOLIS POWER & LIGHT COMPANY


                              By: /s/ John C. Berlier, Jr.
                                   John C. Berlier, Jr.
                                   Vice President
                                   Resource Planning and Rates

                        EMISSIONS CONSTRAINED DISPATCH PLAN
                             Effective January 1, 1995

Economic Dispatch is loading each generating unit so the lowest cost 
generation is called upon first to generate the power needed, thereby
minimizing total electric energy generation cost.  Emissions Constrained
Dispatch is simply Economic Dispatch where the estimated value of the
SO2 allowances being consumed by a unit is included as a part of the
unit's cost of generation.  A lower emitting unit will reflect a
relatively lower emissions cost because it requires fewer sulfur dioxide
(SO2) allowances.

IPL's plan to implement Emissions Constrained Dispatch is to incorporate
SO2 allowance values into the existing Energy Management System (load
dispatching system), which economically dispatches IPL's generation.  As
the generation required (load) increases, the available unit with the
lowest incremental cost is dispatched to meet the increase.  As the
generation demanded decreases, the unit with the highest incremental cost
is dispatched to reduce its generation, thereby minimizing cost.1

Currently, the Energy Management System uses incremental heat rates, along
with fuel and variable operation costs to determine the incremental cost of
generation on each unit in service.  Effective January 1, 1995, SO2 
emissions related costs will be included in each unit's incremental cost
prior to the incremental costs being compared to make the unit dispatch.
The incremental SO2 value will be in units of dollars per million British
Thermal Units ($/MMBTU) and computed by the following guidelines:

        IPL plans to use EPA (Environmental Protection Agency)
        certifiable data for SO2 emission rates in conjunction with
        the incremental value of emission allowances to form the
        emissions dispatch cost in units of $/MMBTU.  Each 
        generating unit affected by the Clean Air Act will have its
        own specific SO2 emissions data input into the Energy 
        Management System at the beginning of each month.  That data
        will remain for the month unless projected coal deliveries
        for the month have an SO2 value that will change the current
        dispatch.  The Fuel Supply Organization will notify the System
        Operation Office of the projected coal delivery SO2 emission
        rate in #SO2/MMBTU, so that a correct So2 emission rate can
        be input into the Energy Management System.

        1  Optimization of unit loadings in the Energy Management System is
constrained by equipment physical limitations such as maximum rate of load
pickup or maximum load reduction rate on a unit as well as contrained by the
maximum and minimum capability of the units.

        IPL's Treasury Organization will not less often than the 10th day
        of each month supply the IPL System Operation Office the incremental
        value of an emission allowance in units of dollars per ton of SO2
        based upon the Cantor Fitzgerald asking price for allowances, or
        other nationally recognized allowance trading market price, for use
        in IPL's emission constrained dispatch on a forward going basis.
        Beginning January 1, 1995, the allowance price that will be used
        for purposes of IPL's emissions constrained dispatch will be the
        asking price for allowances obtained from Cantor Fitzgerald on
        December 30, 1994.  The Treasury Organization will track the
        emission allowance market and if a significant change in
        allowance prices occurs within a given month, the Treasury
        Organization may provide an updated allowance price value to the
        IPL System Operation Office.  The updated allowance price will
        be entered into the Energy Management System and the economic
        dispatch algorithm will be updated accordingly.

The emissions cost will be added with the fuel and variable operating cost
to produce a total dispatch cost.  The total dispatch cost will be combined
with the incremental unit heat rate data to produce the total incremental
dispatch cost as calculated by the following formula:

        INCREMENTAL COST = (Fuel Cost + Emissions Value Divided By
                                Variable Operating Cost) X Incremental
                                Heat Rate

The dimensions for each of the variables is as follows:                 

        Emissions Value, $/MMBTU; Fuel Cost, $/MMBTU; Variable Operating
        Cost $/MMBTU; Incremental Heat Rate, MMBTU/MWH; Allowance Value,
        $/Allowance; Incremental Cost, $/MWH

The dispatch made using the total incremental cost, including SO2 emissions 
related costs, will constitute IPL's Emissions Constrained Dispatch.
